Chemical Structure

Ethyl 4-(m-tolylthio)butanoate CAS 1779128-35-6 chemical structure

Description

The occurrence of Ethyl 4-(m-tolylthio)butanoate is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Ethyl 4-(m-tolylthio)butanoate (CAS 1779128-35-6), a certified reference material (molecular formula C13H18O2S, MW 238.35 g/mol) for analytical method development and quality control.

Structurally, Ethyl 4-(m-tolylthio)butanoate (C13H18O2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 238.35 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures Ethyl 4-(m-tolylthio)butanoate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
